Accenture, IBM and Siebel Systems Help the South African

Government to Increase Tax Revenues, Improve Citizen Service, and

Deliver Greater Operational Efficiency

Siebel Systems, Inc., (Nasdaq:SEBL) a leading provider of business applications software, today announced that the South African Revenue Service, the tax and customs revenue collection arm of the Government of South Africa, has deployed the Siebel Public Sector Single View of the Taxpayer solution in order to integrate multiple taxpayer systems; streamline citizen service processes; and provide staff with a single, comprehensive view of the taxpayer.

Accenture is the lead integrator for deploying Universal Application Network (UAN), which features Siebel Business Integration Applications running on the IBM WebSphere Business Integration platform. UAN is being utilized in combination with Siebel Call Center to enable the new system.

Ken Jarvis, the CIO for the South African Revenue Service, will deliver a keynote detailing the savings and benefits that a single view of the taxpayer has delivered to his organization on April 21st at Siebel User Week 2004 in Cannes, France--Europe's largest CRM event.

"Universal Application Network is providing millions of dollars per week in savings to the South African Revenue Service by releasing previously untapped value from the systems that we already have in place," said Jarvis. "Moreover, by using packaged integration and citizen service applications from Siebel Systems, we have sped our time to deployment by months--enabling us to capitalize on these incredible savings faster than otherwise possible."

Prior to deploying the Siebel Single View of the Taxpayer solution, the South African Revenue Service was facing considerable business integration challenges. Fragmented taxpayer information residing in disparate systems prevented the organization from performing certain tasks, such as accurate debt equalization. This resulted in loss of tax revenues and customs dues, as well as taxpayer frustration with government services.

To address these integration challenges, the South African Revenue Service turned to Accenture, IBM, and Siebel Systems. This joint team worked with the Revenue Service's IT organization to deploy UAN to integrate eight taxpayer systems with an existing deployment of Siebel Call Center, which now provides citizen service personnel with a single, comprehensive view of the taxpayer. The initial deployment, a 200-user pilot trial, was completed in just eight weeks, and the subsequent deployment and rollout nationwide to more than 5,800 users was delivered in less than four months.

"The benefits of business process integration are unambiguous," said Nimish Mehta, Group Vice President UAN, Siebel Systems. "What is not clear for most organizations is how long integration will take, and how expensive it will be. With Siebel Business Integration Applications we are reducing the time, cost, and risk associated with integration, allowing clients such as the South African Revenue Service to focus on streamlining their operations and delivering flexibility and agility to their organization."

With the availability of comprehensive, real-time taxpayer information, the South African Revenue Service has lowered operational costs and improved citizen service by reducing response times for handling tax interactions. Moreover, the agency has dramatically increased revenues by enabling taxpayer service agents to more effectively perform tax liability assessments across products and service lines, ensuring, for example, that refunds are accurately offset against other taxes prior to payment. By increasing tax collections and lowering costs, the South African Revenue Service estimates that the single view of the taxpayer deployment project has paid for itself in less than two months.

The South African Revenue Service plans to continue to deploy Siebel Business Integration Applications throughout its organization. Subsequent implementations will focus on extending the scope of legacy applications connected and delivering more end-to-end business processes.
